BACKGROUND OF THE INVENTION Field of Invention

The invention belongs to the technical field of shower devices, and relates to a shower device.

Related Art

Showering is one of the most commonly used ways to clean the body, nowadays people usually use a shower head when taking a shower. During the shower, first turn on the shower to wet the body, then turn off the shower and apply a body wash on the body and scrub, and finally turn on the shower to rinse off the body wash. This showering method needs to be carried out in three stages. In the middle of the process of applying the body wash, the shower is turned off, resulting in a decrease in temperature, the showering experience is not so pleasant, especially in winter.

In order to improve the comfort and convenience of showering, Chinese Patent Application No. CN201511002107.0; and Chinese Patent Publication No. CN 105395115 A disclosed a shower device with a body wash comprising a body wash feeder, a shower bottle, and a water dispenser valve. The body wash feeder is installed on a shower rod and communicated with a shower waterway, and the shower bottle is installed on a top of the body wash feeder and communicated with an inner cavity of the body wash feeder. The water dispenser valve is installed in a middle of the shower rod, and the body wash feeder is installed on the water dispenser valve and communicated with an inner cavity of the water dispenser valve.

When taking a shower, pull a lever of the body wash feeder outward and release the lever to manually fill a body wash in a quantitative manner, then turn on the water dispenser valve to mix water with the body wash, and then the mixed water is sent to a shower head to spray out. As the showering time passes by, the mixed water is replaced by clean water for rinsing the body. However, due to the constant amount of the body wash that is filled once by pulling the lever, when the mixed water needs to be used continuously, the lever needs to be pulled several times during the showering process, and when clean water needs to be immediately switched for rinsing, switching to clean water cannot be realized immediately, have to wait for the mixed water to be completely used up, and once the lever is misoperated, filling of the body wash cannot be cancelled, clean water can only be discharged after all the mixed body wash is sprayed out, resulting in inconvenience in using the shower device of the prior art.

In order to speed up changing the mixed water into clean water, a quantitative filling amount of the body wash is usually reduced, and the mixed water can be used up as soon as possible by reducing the added amount of the body wash. But this adjusting way can only speed up changing the mixed water into clean water, and cannot make the mixed water change into clean water immediately, and also resulting in the need to increase a frequency of refilling the body wash when there is a need for continuous use of the mixed water. In order to keep the mixed water available for a longer time, a quantitative filling amount of the body wash is usually increased, which in turn leads to a longer waiting time when clean water is needed.

The adjustment frame 13 is connected with a swingable mirror frame, a suspension groove is disposed on the mirror frame, and a razor can be suspended in the suspension groove.

One embodiment of the shower frame 4 is fixedly connected on the wall, and the body wash storage container 1 stores the body wash. During showering, when it needs to apply the body wash, rotating the operating handle 2 e is capable of switching the multi-waterway switching valve 2 to cause the secondary water outlet 2 b to discharge water, when water passes through the mixer 3, the mixer 3 is capable of generating a negative pressure to automatically suck the body wash in the body wash storage container 1 and the outside air into the mixer 3, the water, the air and the body wash are mixed in the mixer 3 to form a mixed body wash, the mixed body wash continues to foam during a flow process, and finally flows out from the foam dispenser 6 in the form of foam, and then use the foam dispenser 6 to apply the foam on the body and scrub. If an amount of the body wash is too much or is too little, adjust a suction flow rate of the body wash by rotating the valve core 3 a through the adjustment knob 3 e in order to adjust a ratio of the body wash in the mixed body wash. If foam is not needed but clean water is needed instead, the secondary water outlet 2 b can be kept discharging water continuously by rotating the valve core 3 a of the mixer 3 to change a cross-sectional area of a communicating port between the body wash inlet channel 3 b 7 and the body wash inlet hole 3 a 1 to zero, so that clean water is capable of flowing out from the foam dispenser 6; clean water is further capable of flowing out from the top shower or the hand-held shower by directly switching the multi-waterway switching valve 2 to cause any one of the two primary water outlets 2 c to discharge clean water.

Since the two showerheads 5 in one embodiment are only connected with the two primary water outlets 2 c of the multi-waterway switching valve 2, the foam dispenser 6 is only connected with the body wash outlet 3 b 3 of the mixer 3, and the water inlet 3 b 1 of the mixer 3 is connected with the secondary water outlet 2 b of the multi-waterway switching valve 2, that is, the foam dispenser 6 is communicated with the multi-waterway switching valve 2 only through the mixer 3, and the mixer 3 is not connected with any one of the two showerheads 5, which avoids a possibility of the body wash entering into any one of the two showerheads 5. Foam only flows out from the foam dispenser 6, and clean water flows out from any one of the two showerheads 5, in order to ensure that when the multi-waterway switching valve 2 is switched to cause any one of the two primary water outlets 2 c to discharge clean water, clean water will flow out from one of the two showerheads 5 instantaneously, thereby clean water switching process is completed instantly without having to wait. At the same time, when water passes through the mixer 3, the mixer 3 is capable of generating a negative pressure with respect to the communicating passage 17 between the body wash storage container 1 and the mixer 3, that is, as long as the body wash inlet channel 3 b 7 and the body wash inlet hole 3 a 1 in the mixer 3 are in a communicated state, when water passes through the mixer 3, the mixer 3 is capable of sucking the body wash in the body wash storage container 1 into the mixer 3 continuously and automatically, so that when the multi-waterway switching valve 2 is switched to cause the secondary water outlet 2 b to discharge clean water, the body wash can be automatically filled, and there is no need for a user to perform other additional manipulations, the foam can be continuously sprayed out from the foam dispenser 6. Moreover, the mixer 3 has an adjustable structure capable of adjusting a sucking flow rate of the body wash or even shutting off the communicating channel 1 f, which facilitates the use of the foam dispenser 6. Therefore, it only needs to manipulate switching the multi-waterway switching valve 2 to cause any one of the two showerheads 5 to discharge clean water instantaneously, while switching to the foam dispenser 6 is capable of discharging foam continuously, and a proportion of the body wash in the foam can be adjusted, additional manipulations are not required when switching, there is no need to wait and it is convenient to use. Therefore, the invention improves the convenience of using the shower device.
